Application led May 11, 1909. Serial No. 495,298.

To all whom it may concern:

Beit known that I, HAMILTON A. GORDON, a citizen of the United States, residing at East Orange, in the county of Essex, State of New Jersey, have invented certain new and useful Im rovements in Turnstiles; and

'I do hereby eclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains .to make and use the same.

The present invention relates to improvements in turnstiles, and more particularly in those which are attached to or employed in connection with a registering mechanism, forindicating the number of persons who vpass through a passageway, `wherein the turnstile is located, intoan mclosure.

In general, the objectA of the invention is to roduce an extremely simple', inexpensive, and) efficient turnstile of the type specled above, which includes among itspessential parts, a head and a series of radially arranged arms secured thereto, the arms being vconnected in sucha mannertothe head as to successively dro into vertical position during a portion o their rotation, so' as not to interfere with the ticket puncher or collector who is thus enabled to stand nearer to the turnstile than has heretofore been'possible.v

To't'his end, the arms arearranged to travel along a track composed of a pair of spaced members whose rear portions are bent downward, thus causing each arm to automatignated by the same reference characters throughout the several views.

Of' the drawings, Figure 1 is a plan view of the improved turnstile. v Fig. 2 1s a front elevation thereof. Fig. 3 is a vertical section taken on the line 3.-3 of Fig. 1. Fig. 4 is a horizontal section taken on the line 4--4 of Fig. 2.- Fig. 5 is a horizontal sec tiontaken on the lin'e 5-,5 of Fig. 3. Fig. 6 is an enlarged Idetail perspective view of one of It'he swivel connections between the arms and head. Fig. 7 is an enlarged detail perspective view of two of the links of the chain. Fig. 8 is a fragmentaldetai'l view of one ofthe arms, showing the roller atl".

tached thereto. Fig. 9 is a fragmenta-l side elevation of the turnstile. Fig. 10 is an enlarged detail view of one of the stop plates secured to the head.

Referring more particularly vto the drawings, 10 designates the vertical main shaft of the turnstile, 11 the base plate wherein the lower end of the shaft is journaled, and 12'the top plate or head thread-ed upon the upper end of said shaft, which 'latter carries at such point a disk 13 mounted upon an upstanding pin 14 set into the shaftend, said disk beingl provided with a series 'of lugs 15 arranged forv successive engagement with one of the wheels of agregistering apparatus (not shown) of any preferred lty e.

The arms 17 of the turnstile are of tll'xe usual number, z. e., four, and are rivetedV adjacent their inner ends to 'a chain Ay composed of a series of plates 18 connected together by hinge pins 19, which extend loosely throughthe re istering openings 'formed in the knuckleswith which the plates are pro vided at their mutually adjacent edges. Each pin has secured to its ends a l.pair of rollers 20 arranged to travel upon thev lower member of the trackB. This track consists of spaced upper and-lower annular plat-es 21 and 22'supported, respectively, byv rear and front uprights 23 and 24 disposed lwithinthe turnstile casing C, a-s shown. The front or major portions a and a" of the two plates occupy parallel horizontal planes, and the rear or minor portions ZJ and b thereof occupy parallel vertical planes, the downwardly inclined connecting portions 0..-and c being likewise parallel. The distance between the two plates is the. lsame at all points.

The arms 17 are connected to the head 12 by means of the hinge joints D, one of which is illustrated in 6. Each of these joints A formed with a depending shoulder 2 .l hich is hinged a second disk 27 secured t the extreme inner Vend of one of the arms, the-diskportion 25 of each joint havlng an upstandmg 4pin 28 which extends loosely through in saint` head 12, andv has threaded uponits upper an opening 4formed a fastening nut 29 end. Thus it will be seen that each arm is capablevboth of a turnstile are inno danger of lstrikin the track wit bodily swinging movement in a vertical plane, and ofa turning, movement lor rotaall times by means of stop plates 30 bolted to the periphery of the head 12, each of said plates having its lower portion recessed 4in such a manner as to provide a pair of depending ingers 35 and 36 of unequal lengths, between which lingers the arms it during their travel along the horizontal stretch of the track. c These lingers also serve to'prevent any rearward movement of the arms independently of the head. f'

Shaft 10 is provided adjacent its lower end withv a four-sided wheel 31 and a ratchet wheel 32, the concaved edges ofthe sides of the former wheel being engaged by the free ends of a pair of Adiametrically opposite leaf springs 33 secured to the base plate 11, which latter-carries a spring pressed pawl 34 arranged to engagel the teeth of the ratchet wheel. The combined action of the wheel 31 and the springs causes the Ishaft to' make exactly'a quarter revolution each time the turnstile is actuated, thus insuring the extension of one of the arms across the passageway D at the termination of each actuation. The pawll and ratchet coperate vin holding the shaft against backward rotation.

The major or horizontal portions a and a of the two plates 21 and 22, which form the guide B project toward and extend a slight.

stance across the passageway, while the minor portions b vand b of said lplates extend downward in close proximity .to shaft l0. By reason of this arrangement," it will bea parent that during the rotation of said sha t, the arms 17 will move in a horizontal plane across the passagewa andon reaching the inclined portion o the track will drop, or move downwardlyassuming avertical position, when the ortio-n of the track is reached, thus enabling the ticket puncherfor, .collector to take his stand ldirectly oppositefthe turnstile and close to the shaft thereof, instead of tothe rear' or at one side of the turnstile, as has been necessaryheretofore. Moreover, the arms ofthe or otherwise interfering with the oflicial, w o is thus free to continue his occupation without fear of interruption.

In 'order to rmi the arms to .move along l) the least possible friction,

each arm has' formed therein adjacent the point of'itsatt'achment to the chain, a pair of recesses 37 each of which is bridged ly a pin 38 havin a roller 39 rotatably mounted thereon, as s own in Fig. 8.

VThe front upffght' 23 located within the casing C is farmed with a lateral arm-40 having attached thereto a collar 41through which the shaft`10 loosely extends, said 'shaft and dis osed between same andthe i `rail sai connection comprising a series of Ibeing steadied in this manner, as will be apparent. The shaft is also held against any upward movement by means'of a' collar 42,

which is fastened'theretoand is arranged to' bear againsttlie above mentioned collar 41.

The casing C is so constructed as to completely inclosethe entire turnstile ywith the exception of the arm which projects into the passageway. This casing maybe briey described as comprising a vertically disposed cylindrical body portion 43 and -two win 44 and 45 located upon opposite sides thereof, as shown in Fig. 2, the edge portions of the wings being formed Awith curved slots 46, whose up er ends open into a-single horizontal slot 4 formed in the front faces of said wings and continuin across the adjacent surface of the casing ody, the arms 17 moving outwardly through the left hand `portion of the last mentioned slot, and in-v wardly through' the right hand portion thereof, as will be obvious.
